← Nature & AnimalsWhich benefit results as CAM photosynthesis overcomes photorespiration?
A)Reduced carbon fixation
B)Decreased biomass production
C)Increased water-use efficiency✓
D)Compromised CO2 availability
💡 Explanation
CAM plants use temporal separation because stomata open at night to fix CO2, undergoing crassulacean acid metabolism, thereby raising water-use efficiency. This is rather than fixing CO2 during the day when transpiration is higher and water is lost.
